The role of the fixation location in inhibition of return

Can J Exp Psychol. 2000 Sep;54(3):186-95. doi: 10.1037/h0087340.

Abstract

Experiments that have examined inhibition of return (IOR) have typically used trial sequences in which attention is reoriented to a central fixation location between the presentation of the peripheral cue(s) and the target. In examining the role of the fixation location in IOR, three experiments were conducted in which an exogenous cue was used to reorient attention following a peripheral cue and before the appearance of a target. However, this cue occurred at either the traditional central fixation location or a nonfixated location. The results indicate that reorienting attention to a fixated location results in a significant reduction in the inhibitory effect. The results from the study suggest that IOR could serve as a mechanism that improves the efficiency of visual searches.
